How To Repair Electric Scooter

Quick and Easy Tutorial on how to Diagnose and Repair your Brushless DC Motor

The simple brushless DC hub motor. It is the i thing that revolutionized the whole concept of Personal Electric Vehicles (PEVs).

Never before has a propulsion device been placed into such a small package consisting of only 3 main components that are low maintenance and easy to utilise:

1. Stator with permanent magnets
2. Electromagnet rotor with bearings
3. Hall sensor controller board

The rest of the components are just wires and hub covers.

We will not go into too much detail as this is the DIY tutorial simply as y'all tin see the graphic above, due to the simplicity of the design, there are only a few components that can be worn out or damaged:

1. Bearings. The motor bearings tin be considered worn out once yous feel that they do not scroll equally smoothly as before or if they just completely plummet, information technology can cause the motor is get jammed. The bearings can typically terminal for at least the first 5000km of the east-scooter's life.
2. Faulty controller lath or sensors. For some motors without hall sensors, in that location are just 3 motor wires running from the motor controller out of the motor. Those are the simplest type so if at that place are any issues, the trouble should be just with the wires. The wires by itself does not go damaged but due to accidents, they could be damaged externally. The control board rarely get damaged unless h2o enters the motor as it is a passive excursion.
3. For motors with the hall sensors that feedback into the ESC (controller of the due east-scooter), the the wires are more complicated. There are the iii motor wires and the 5 or six hall effect sensor wires. The graphic beneath shows the 3 hall effect sensors with the (blue) command lath. Like before, the control board will not really become damaged. Still, the sensors do due to water, heat, vibration or poor quality.

Really. Thats it. You either fix the bearings, wires or sensors.

Heres Part 1 on how to prepare the wires of the ZERO 9 motor which is a standard 500W/600W brushless DC motor:

If your electric motor is a divide hub with screws on both sides, you tin remove the stator from the magnetic rotor easily equally shown in this video:

However, if your hub motor is NOT a split hub, you have to use this method to dissever the stator from the electric rotor:

Office ii will be on how to replace the Hall sensors so stay tuned…
